c integer- std string conversion Simple function

Question

Problem  I have an integer  this integer needs to be converted to a stl  string type    In the past  I ve used stringstream to do a conversion  and that s just kind of cumbersome  I know the C way is to do a sprintf  but I d much rather do a C   method that is typesafe er    Is there a better way to do this    Here is the stringstream approach I have used in the past   std  string intToString int i        std  stringstream ss      std  string s      ss  lt  lt  i      s   ss str         return s      Of course  this could be rewritten as so   template lt class T gt  std  string t to string T i        std  stringstream ss      std  string s      ss  lt  lt  i      s   ss str         return s      However  I have the notion that this is a fairly  heavy-weight  implementation   Zan noted that the invocation is pretty nice  however   std  string s   t to string my integer     At any rate  a nicer way would be    nice       Related       Alternative to itoa   for converting integer to string C

Like mentioned earlier  I d recommend boost lexical cast  Not only does it have a fairly nice syntax    include  lt boost lexical cast hpp gt  std  string s   boost  lexical cast lt std  string gt  i     it also provides some safety   try    std  string s   boost  lexical cast lt std  string gt  i    catch boost  bad lexical cast  amp

Not really  in the standard   Some implementations have a nonstandard itoa   function  and you could look up Boost s lexical cast  but if you stick to the standard it s pretty much a choice between stringstream and sprintf    snprintf   if you ve got it

Now in c  11 we have   include  lt string gt  string s   std  to string 123     Link to reference  http   en cppreference com w cpp string basic string to string
